The Zwilling J.A. Henckels Professional S series known as Pro S, delivers outstanding cutting performance and used worldwide by professional & home chefs. This entire collection features precision forged knives made from a single piece of Zwilling J.A. Henckels exclusive high-carbon stainless steel. As a result, the knives have improved quality consistency, lasting sharpness, and perfect geometry. In addition, the steel blade goes through a special ice-hardening process called Friodur. This process changes the molecular structure of the steel improving the cutting properties providing a remarkably sharp blade and ensures a long lasting cutting edge. Each knife is precision honed and laser controlled to assure the cutting edge is accurate along the full length of the blade. The blade is enhanced with a traditional 3-riveted comfortable handle.
